perf python: Use exception to propagate errors
We were using pr_debug to tell the user about not being able to parse a sample where we should really use the python way of reporting errors: exceptions. Fixes this problem: [root@emilia ~]# python >>> import perf Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: eprintf >>> [root@emilia ~] As we want to keep the objects linked in the python binding (and in the future in a shared library) minimal.
